I love the little darlings in the front row - on the left, the little one wearing what looks like a kilt, and on the right, the curly mop with the stripey pants

Anyway, I haven't done much with this but I did split it through the middle and pull it apart to where I think the two halves would have been originally - as you can see, there's a huge gap down the middle

Tidied up a little in top left corner, but don't have time to do more unfortunately.
Prue
Added: actually, I think they probably need to be slightly further apart than this, looking at the alignments of shoulders and heads down the split
